* removed <term> wrappers
* added <const> wrappers
* removed <role><term> construct, now <rolename>R</rolename>
constructs.
* added <variables> section.
* variable substitutions are followed through in runs. Thus, only
unbound variables occur in the semitrace.
* added the untested claims back in, so that all events in a
role/semitrace are now shown. Note that they can be disabled
again by using the new '-H' switch.
- Some fixes for protocols that do not include matching send/read
combo's. In particular, the max encryption level method ranged over
the sends; now over all events. Maybe it can range over read events
only?
* Hiding of 'discouraged' options: these should not be used by e.g. students.
* Hiding of 'unimportant' options: not harmful, but not often used either.
